Module and method for driving elongate flexible medical instruments and associated robotic system

摘要

The module has a channel (59) extending along direction, and drive pulleys (31a-31d) provided on a side of the channel. The pulleys include a drive surface. An elongated band includes portions (61a, 61b) comprising an internal face cooperating with the drive surface of the pulleys and an opposed external face cooperating with a flexible medical organ. The band is stretched by the pulleys with an elongated portion extending along the channel according to the direction. One of the pulleys is motorized. An adjusting device (34) is placed between the pulleys. An independent claim is also included for a robotic system.
